Yeah, but even now you have people like Christoph Hellwig turning up on e.g. the glibc list when probe point adding patches were proposed, saying 'no, uprobes will never exist in this form'. So uprobes may exist but some kernel hackers are trying as hard as possible to make sure they stay useless and out of *every* package's upstream.

I thought I read about work to make SystemTap work with procfs. Any idea what is happening there (Frank?) Although something seems to be happening currently with uprobes, and Christoph Hellwig seemed to be actively (positively) involved in the discussion (see http://lkml.org/lkml/2010/7/27/121).

I'm not quite sure which effort you may be referring to.

Yes. It is unfortunate though that instructions of the form "Don't SYMBOL_EXPORT this facility [since you-know-who might use it]" are still the order of the day.
